Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide.Most AES calculations are done in a particular finite field.The AES encryption process operates on a 4x4 byte matrix, also known as "State", who

About OpenSSL OpenSSL
SSL is an abbreviation for the Secure Socket Layer protocol, which provides covert transmission over the Internet. Netscape Company introduced the SSL protocol standard at the same time as the first web browser, there are now 3.0 versions. SSL employs public key technology. The goal is to ensure the confidentiality and reliability of communication between two applications, enabling simultaneous support both on the server side and
First, the basic concept of AES algorithm
AES is the abbreviation of Advanced Encryption Standard (Advanced encryption Standard), AES has the following three characteristics.
1 AES is symmetric encryption algorithm
The concept of symmetric encryption, Baidu Encyclopedia is this explanation: in the symmetric encryption algorithm, the data originator of the plaintext (raw data) and encryption key together through a special encryption algorithm processin
: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After five years of selection process, the Advanced Encryption Standard was issued by the National Institute of Standards and Technology (NIST) on November 26, 2001 in FIPS PUB 197
.
Asymmetric encryption algorithm that uses two pairs of keys that are completely different but perfectly matched: the public key and the private key. When encrypting a file using an asymmetric encryption algorithm, the process of encrypting and decrypting the plaintext is accomplished only by using a matching pair of public and private keys.
3.1: Symmetric encryption:To create a Nodejs file Cipher.js, enter the following:var crypto = require (' crypto '); Load Crypto library Console.l
Openssl is an open-source product used to implement the SSL protocol. It consists of three parts: cryptographic algorithm library, application program, and SSL protocol library. Openssl implements most of the algorithms required by the SSL protocol.
Next I will introduce how to use Openssl for symmetric encryption of files.
I. Openssl supports the following encryption algorithms:
-Aes-128-cbc-aes-128-cfb-aes-128-cfb1
-Aes-128-cfb8-aes-128-ecb-aes-128-
